??? You're gonna be sending yeast sludge through your regulator if you dont cut your diptube off real short. I'm not sure how this is exactly going to work. Does anyone know how much pressure could build up in a corny under these circumstances without letting off the pressure? I would personally just go to your local supply and get some more CO2.

Those emergancy valves are supposed to get up to 130 PSI. So even if you try to get lots of fermentation going....you're probably going to get enough pressure to get an enemic burp from a normal CO2 regulator (because it's designed for pressure ranges of 500 - 1200 PSI).

I agree, it's easier just to get out there and get your tank filled: with this, it seems like it's a lot of work for little gains.

There are some other compounds produced in some fermentations. I know a lot have a very sulfery smell. I wouldn't want that going into my keg of beer.

You would be better off priming the keg and letting pressure build up inside the keg. You will probably have enough pressure to dispense for a little bit. That will tide you over so you can go get your tank refilled.

A. It will work, gas to gas.
B. Lots of luck modifying the regulator. I wouldn't bother.
